From the publisher:

This book talks about the device and use of Mac OS X 10.5 Leopard.
Starting with the basics - how to handle folders and files, register
users, install programs - you will become acquainted with solving more
complex tasks, such as creating a small local network, setting up
Internet programs, and interacting with other operating systems. You
will learn how to quickly find the necessary documents, how to deal
with many open windows and how to protect your data from loss. And
also many other things that will help you work on the Mac better and
more efficiently.
